I/O_Pro Scalability

Use RAID-0 for Performance

I/O_Pro offers striping (i.e. RAID-0) to increase performance of I/O Read & Write functions

Targeted for applications using large size files such as desktop publishing & CAD software
Accelerates sustained Read/Writes by 70%
Striping across channels or cards allowed
Strip size range from 4K to 1M
Support uneven striping for efficient utilization of total available disk drive space

Ą@

Striping of Unequal disk drives

Ą@

Example: 7G RAID-0 partition w/ 3 uneven disks
